<h1 class="topictitle1">A Backup Job Fails to Be Executed, and a Message Is Displayed in the Job Details, Indicating the Failure of Instructing Client xx to Complete the Job of Backing Up Disk xx or the Failure of Instructing Client xx to Back Up Disk xx</h1>
<div><div class="section"><h4 class="sectiontitle">Symptom</h4><p>A backup job fails to be executed, and a message is displayed in the job details, indicating the failure of instructing client <em>xx</em> to complete the job of backing up disk <em>xx</em> or the failure of instructing client <em>xx</em> to back up disk <em>xx</em>.</p>
</div>
<div class="section"><h4 class="sectiontitle">Possible Causes</h4><p>After data is backed up using the client, disk shutdown by invoking the VMware production environment times out. As a result, the backup job fails.</p>
</div>
<div class="section"><h4 class="sectiontitle">Troubleshooting</h4><ol><li><span>Modify the configuration file of the OceanProtect.</span><p><ol type="a"><li>Use PuTTY to log in to the CLI of the <span>OceanProtect</span> as user <strong>admin</strong> through the management IP address.</li><li>Run the following command to switch to the developer mode:<pre class="screen">change user_mode current_mode user_mode=developer</pre>
</li><li>Run the following command to set the timeout interval. The default timeout interval is 1800000 (30 minutes). In the example, the timeout interval is changed to 3600000 (60 minutes). You can change the timeout interval based on the site requirements.<pre class="screen">change container general namespace=dpa pod_name=infrastructure-0 container_name=om params=get.sh\scurl_url\sset_upgrade\svmware-conf\sPromiseWaitTimeout\s3600000</pre>
</li></ol>
</p></li><li><span>Modify the configuration file of the host where the client is installed. <span class="uicontrol"><b>/opt</b></span> indicates the client installation directory. Replace it with the actual directory.</span><p><ol type="a"><li>Run the following command to open the configuration file of the host where the client is installed:<pre class="screen">vi /opt/DataBackup/ProtectClient/ProtectClient-E/conf/agent_cfg.xml</pre>
</li><li>Change the values of <strong>vddkapi_timeout</strong> and <strong>api_invoking_time_interval</strong> from <strong>1800</strong> to <strong>3600</strong>. Value <strong>1800</strong> indicates 30 minutes, and value <strong>3600</strong> indicates 60 minutes. You can change the values based on the site requirements.</li><li>Press <strong>Esc</strong> and enter <strong>:wq</strong> to save the file.</li><li>Run the following command to restart the client service:<pre class="screen">sh /opt/DataBackup/ProtectClient/stop.sh &amp;&amp; sh /opt/DataBackup/ProtectClient/start.sh</pre>
</li></ol>
</p></li><li><span>Perform the backup job again.</span><p><ul><li>If the job retry succeeds, no further action is required.</li><li>If the retry fails, collect logs and contact technical support engineers for assistance.</li></ul>
